Bad knock
2004 5.4 truck has 174400 on it.. I have always had the little injector tick.. What started yesterday is a loud knock.. At idle it just a load tick. When I bump up the rpms it turns into a knock.. I am 90% it is the bottom end.. I really don't think its phasers or anything up top.. When I'm under the truck it sounds like in the oil pan.. What you boys think?? I have already talked to an engine shop.. Want to hear what the fellas got to say before I do anything.

First eliminate the not-as-bad and check the exhaust manifolds, I say that because I read that is a common issue. BUT if it IS main bearings, those can be replaced.......just a lot of hours involved. With that kind of mileage though, I'd just get a remanufactured engine and be done with it.
Best of luck......been there done that(with a GMC).

Checked manifolds first thing.. Right now I plan on parking truck till I get time to get it dropped off at the engine shop. If its main bearings how much would a guy dare drive it. I'm about 80 miles from said engine shop. Would rather not haul it down, but I don't want to cause any more damage. Any input would be great.. Thx guys.

Best of luck from somebody who has "been there done that".

Today I changed my oil and I went with a 10w30. Still have my knocking noise.. But why I posting this is because I cannot believe how much better the engine as a whole runs.. So silent and smooth it is crazy... To damn bad there is a rod bearing knock/ rattle.. Still have no intension of driving the truck other than getting it on a trailer.. Anyways, I really am impressed with the heavier oil. After the repair I will be running 5w30 for sure..
